Seye Abimbola: Reflections on the non-existent health system

11 Jan, 11 | by BMJ

Imagine a country without a health system; imagine the chaos, and inefficiency. In such a setting, the only form of health systems research necessary would be to generate evidence towards achieving universal coverage. Research will not only be about which interventions work, but where and how the interventions would be most optimal. Indeed, if we push our understanding of what constitutes a health system to include its ideals, it becomes clear that the thought experiment is not quite so far-fetched. Especially ideals which according to the WHO include improving population health, protecting people from the cost of ill-health, providing health care with fair treatment to all.

The world is at a watershed, on the brink of monumental change in what constitutes health care and life in general so much that the absence of health systems may even be desirable. To combat the challenge of non-communicable diseases (NCDs), we may even want to wish away current health systems altogether. Factors that are changing the way we perceive life and health include communication with internet and mobile connectivity, population ageing, the shift from acute and inpatient care to long-term care, and management of risk factors instead of disease states in themselves.

The new paradigm for service delivery, a shift from infectious disease of earlier centuries, will be self-management, risk factor management (hypertension, diet, inactivity, tobacco, alcohol), chronic disease and comorbidity. The question then arises as to how we may  build a health system for the 21st century. This makes the thought experiment of a country without a health system necessary: it sets the mind free for uncluttered imagination and allows one to think as if one is building afresh.

The non-health components of society alongside how they might help support a health system are factors that come readily to mind when one thinks about a non-existent health system. In the case of Nigeria, two prescriptions presented themselves: the potential roles of mobile phones and patent medicine vendors in strengthening primary health care. In an email that challenged them to make suggestions as if Nigeria did not have a health system, I asked my old medical school classmates  what to say about how we might improve the Nigerian health system. The suggestions were mostly about the need to strengthen primary care, and increase access to health care, especially for the poor.

There is a revolution sweeping through Nigeria with mobile phone use, which rose exponentially in both rural and urban settings following its introduction in 1999. Nigeria has one of the fastest growing mobile phone markets in the world. Mobile phones have had immense impact on economic and social life, but their potential benefits in health care delivery have not been investigated. The research challenge in Nigeria is to study how we may structure our health system to facilitate universal coverage based on remote consulting.

NCDs management struck me as particularly amenable to this technology. For example, the increasing prevalence of cardiovascular diseases in sub-Saharan Africa results in a large number of patients presenting as emergencies, owing to poor access to health care due to cost, distance and poor self-monitoring (1). It is important that we look at how to explore the use of mobile phones to collect population level data on NCDs risk factors and investigate the potential of remote consulting with mobile phones following self-diagnosis and monitoring (e.g. of blood pressure and blood glucose level). This may help provide cost-effective alternative strategies for managing risk factors and to prevent avoidable emergency presentation, improve care for remote patients, reduce patient load in primary care and in primary care nestled within tertiary centres.

Research into adapting trends in communication, information and health seeking behaviour, to maximise access is an imperative.  Presently, about 70% of the health budget in Nigeria goes to hospital and tertiary care, but few hospitals serve a huge population of about 150 million. Hospitals are often overstretched from overcrowding by out-patients with NCDs and in-patients with fatal but avoidable emergencies. One way to address this is to harness the capacity of patent medicine vendors for primary care as highlighted in a Nigerian newspaper article: “Some of the pharmacies (read patent medicine vendors) have served their neighbourhood long enough that they are now trusted sometimes more than hospitals” and “their proximity makes them the doctors next door.”

There is at least one drug shop in every three streets in Nigeria, trusted outreach facilities where trained health workers could be made assessable to people at no extra cost. Many children die of malaria because of late presentation after three to four days’ consultation at the “Pharmacy” without improvement. If people have structures and systems to which they have grown to be loyal and accustomed, we must opt to build health systems around them.

It is safe to assume that every country has a health system, no matter how dysfunctional. But it is also true that when held to high standards, only few would measure up. The challenges of health are now global, and the theatre of research activity for building the 21st century health system should be the poorer countries of the world. For rich countries, ossified tradition is a major obstacle to research for change. The challenge is upon us to see with new eyes, and to think as if we were indeed blessed with a virginal, unpainted health care landscape with the task of building systems from scratch.

Really, if there wasn’t any health system in place, and we had to create something anew, in what ways do you think the new system would differ from the present? I look forward to your suggestions and ideas.

    Inspiring article – I qualified in Nigeria 15 years ago and it seems the situation is still the same. My final year research project examined the rate of use of the local patent medicine sellers in the management of STIs in a suburb of Lagos and confirmed the high rate of use and often poor treatmentof common STIs. It is probably high time we stated looking at ways of reducing the rich poor divide in health care provision in Nigeria.

    Seye makes very interesting and compelling points in his blog. And I agree that a lot of what he suggests are worth pursuing, at least, worthy of some form of research.

    But bear in mind that Five previous National Health Plans highlighted, largely on paper, the importance of anchoring the health system to a functional primary health care. Indeed the National Primary Health Care Agency where Seye works is a direct baby of one of such plans ( Long Live the memory of Late Professor Olikoye Ransome-Kuti, former two-time Federal Minister of Health).
    The impact of mobile telephony in health care delivery is an cute topic in many fora across the globe, but especially in subsaharan Africa including Nigeria the most populous country in Africa. There are only the problem of level of literacy ( less than 47% in Nigeria); connectivity ( Nigeria is reputed for its paralytic power supply including solar); cost to end-users ( not to be underplayed in a country where over 80% live on less than $1 a day); etc.
    It appears that the public according to Seye's suggestion will record their Blood Pressure for instance and transmit it through IT to their practitioner. However shows that even university graduates do struggle with taking their Blood Pressure even with using automated machines ( which are not cheap at all) talk less of the illiterate village farmer, fisherman, market woman and village housewife. Not a minor challenge!
    The collateral effect of trying to use IT to prevent, detect and control the NCDs will be an unparalleled spread of currently unregulated illicit self medication, un-educated prescribing by patent medicine vendors and even pharmacies ( in one state in Nigeria there are less than 12 pharmacists for a population of three million).
    It will be very nice to use IT in a new 21st century health system in Nigeria but the reality is that we must not let be carried away by the ease with which those of us ( less than 20% of the population) who reside in the capital cities such as Abuja can purchase, access, use and even modify IT.
    The BMJ recently carried the review of a book titled, 'Whole System Change of Failing Health Systems' which narrates a 4-year experience in such exercise in a state in Nigeria between 2004-2008.
